A "sky pool" that will appear to float in the air ten storeys up, has been unveiled for a new devlopment by property developer Ballymoore in the Nine Elms, district of London.

The pool will measure around 25m long, and will allow pedestrians passing underneath to watch swimmers above them.

The glass will be around eight inches thick, with the water around four foot deep. Unfortunately for swim fans who aren't planning on buying an apartment there, only residents of the building will be able to use the pool.

An artist's impression shows the transparent and structure free swimming pool will be 25 metres long, five metres wide and three metres deep.

A 'Sky Deck' - at the top of the two buildings - will also feature a spa, summer bar and Orangery for residents to relax.

Swimmers in the pool can enjoy a view of the Palace of Westminster as they practice their front crawl.

It's part of the ongoing devlopment of Nine Elms, which will also see the new American Embassy built on the site.

Embassy Gardens - as the new development will be called - will see the swimming pool constructed as a "bridge" between two apartment blocks
